DUMPlNG-WAGON.

Specification of Letters Patent.

Patented May 28, 1907.

Application filed January 28,1907. Serial No. 354,562.

To all whom it may concern.-

Be it known that I, RAYMOND S. O. Fow, a citizen of the United States,and a resident of the city of Trenton, in the county of Mercer and Stateof New Jersey, have invented certain new and useful Improvements inDumping-\Vagons, of which the following is a specification.

My invention relates to dumping wagons of that type in which the bottomis adapted to drop and discharge the load contained in the wagon underthe same.

The objects of my invention are to provide simple and efficient meansfor operating the dropping bottom of said wagon, so as to discharge theloads carried therein with facility, and to properly close and supportsaid bottom when the wagon is loaded.

In the accompanying drawings forming a part of this specification,Figure 1 is a perspective view of the body of a dumping wagon embodyingmy invention. Fig. 2 is a view of the under side of a wagon embodying mysaid improvement. Fig. 3 is a rear view of such wagon, showing thebottom thereof closed. Fig. 4 is a similar view showing the bottompartly opened. Fig. 5 is a front view of such wagon embodying myinvention; and

Fig. 6 is a detall view showing the operating mechanism of the windlasslused in closing the bottom of the wagon afterthe discharge of its load.

1 is the body of the wagon having four permanently closed sides, andprovided with two swinging bottom sections, 2, 3. These sections, 2, 3,are boimd and strengthened at their free edges by metal strips, 4, 5,which are riveted or otherwise fastened to the material forming saidbottom sections. One of said sections is also provided with the metaltongue 6, which is intended to cover and close the joint formed betweenthe two sections, 2, 3, when brought together, thus preventing theleakage of fine materials which may be carried in the,wagon body. At theforward end of the wagonbody is located a Windlass, consisting ofgadrum, 7, with means for operating the same. this drum, 7, and adapted tothereon, are two chains, 8, 9.

be wound cross each other at a point between the drum, 7, on which theyare wound, and the rings,

Fastened to As will be. noted (see Figs. 1 and 5) these chains, 8, 9,

10, 11, which are fastened, respectively, upon the forward ends of thefree sides of the bottom sections, 2, 3. The chain, 9, after passingthrough the ring, 10, crosses under the swinging bottom section, 2,through the ring, 12, and the ring or eye, 13, formed in the upper partof one side of the wagon body, thence, over the sheave, 14, and down tothe eye, 15, to which it is made fast. The cham, 8, after passing fromsaid drum, 7, through the ring, 11, and from thence to and through thering, 16, passes from thence to and through the ring or eye, 17 in thetop of the rear end of the other side of the wagon body, through saideye, 17, and over the sheave, 18, and down to the eye, 19, to which itis made fast. The sheaves, 14, and 18, are sustained by the brace, 20,which is made fast at its ends to the sides of the wagon body, and ismade sufficiently strong to support the load carried on said sheaves.The drum, 7, of the Windlass is journaled at its ends in the sides ofthe wagon body, as shown in Figs. 1 and 2. At one end of the drum, 7, isfastened the ratchet wheel 21. This ratchet wheel is provided with twoseries of teeth or serrations, 22, 23, shown in Figs. 1, 2 and 3. Theseries, 22, are formed on the periphery of the ratchet, while the seriesof teeth, 23, are formed in a circle on one side or face of the ratchet.

24 is a hand lever which is swiveled on the drum, 7, and is adapted toengage with the teeth of the series, 23, on the side of the ratchet. Thedetent pawl, 25, is arranged so as to engage with the peripheral teethof the series, 22. This pawl, 25, is connected by a rod, 26, with acrank lever, 27. At one end this crank lever, 27, is provided with atreadle, 28, and at its other end is weighted by the ball, 29. The pawl,25, is mounted on a frame, 30, on which also is formed a cam guard, 31.

The operation of the wagon is as follows The swinging bottom sectionsbeing closed up tightly against the body, the wagon may be loaded. Whenit is desired to dump the load the operator moves the lever, 24, backtoward the position shown in Fig. 1, taking the pressure of theperipheral teeth, 22, ofi of the detent pawl, 25. Pressure of the footis then apphed to the treadle, 28, and the ball,

29, is thrown over the center and into the- 2, 3, depresses them,simultaneously drawing the chains, 8 and 9 through the various rings andeyes and over the sheaves, 14- and 16,

and unwinds said chains from until the swinging bottom sections, 2 and3, approximate a vertical position, the load then falling to the ground.To close the bottom of the wagon the operator throwsback the weight, 29,to the position indicated by full linesin Fig. 6-, and asshown inFig. 1. This brings the detent pawl in contact with the peripheral-teethof the-ratchet. Hethen forces the lever, 24:, backward and forward, eachbackward throw of the lever bringing it in contact with the teeth, 23,on the side of the ratchet, and the drum is revolved and the chains 8and 9 are wound thereon until the two swinging bottom portions 2 and 3areFagain brought into the position indicated in i 3.

In order to prevent the locking of the two swinging bottom portions, 2and 3, by im proper contact of the tongue, 6, with the .opposing edge ofthe bottom portion, 2, the mechanism is so arranged as to provide forthe closing of the bottom portion, 3, against the lower edge ofv thewagon body slightly before the swinging section 2 is brought up thereto.This may be arranged for in various ways. The chain, 8, may be made alink shorter than the chain, 9, or that portion of the drum, 7, uponwhich said chain 8 is wound. may be made of a slightly larger diameterthan the portion upon which the chain 9 is wound; but I prefer, as asimpler method, to make the chain 8 one link shorter than the chain 9. I

By arranging theoperating chains 8 and'Q,

as shown, I procure an exceedingly effective,

support and brace for the wagon body 'with out the use of additionaldevices, other than the hinges, 32, connecting the bottom sections, 2,3, with the body, 1. By disposing the said chains in the mannerindicated, I

provide support for each bottom section at five different points locatedonthe free and,

hinged sides thereof, and'also pass the chains diagonally beneath theforward portions ofthe sections, thus affording an effective brace andclamp to the entire wagon body.

For convenience in illustration, I have shownthe lever, 24, as thrownback from-the cam guard, 31, but its normal position when the wagon isloaded-is its forwardposition,

Where it is heldbetween the brace, 30, and

the drum, 7.,

the cam guard, 31. order to prevent any accident occurring through thelever being thrown suddenly forward in the event of the detent pawl, 25,becoming in any way disengaged from the teeth, 22. body Having thusdescribed my invention, I claim:
